[saxon] Any tips for using Saxon on a 64-bit, quad-core platform?

Hi,
I've got a new PC with plenty of RAM (say 12GB), running 64-bit Vista Ultimate.
To make best use of this, how should Saxon (Java) be installed and
used from the command line?
What about Saxon.NET? I guess that nothing is needed, is this right?
Is there any way to take advantage of the four cores (besides the
obvious approach of running four instances of Saxon simultaneously)?
